 Mr. C. Holman-Hunt) ; Sumatra (Kandg. Ampat, Lower Padang ; Gunung-Agung, 

 Palembang, 5,000 ft. ; S. E. Serdang, ca. 1,000 ft. ; Engano Island, Benkulen Residency ; 

 also specimens from Médan, Sumatra, submitted by W. Guy Babault) ; Borneo (Mts.

Also several specimens of the variety anipunctus, Zang, from Chapa and Lao Kay, 

 Tonkin, and from Cambodia, presented by Mr. Vitalis de Salvaza. 



Length 1 1-7-20-5 mm. 



The varietal form anipunctus differs from the typical form only in having the pronotum 

 somewhat sparsely, though extensively, punctured in the anterior angles and round about 

 the scars, instead of densely punctured at the sides from end to end ; and in having the 

 posterior intermediate areas of the metasternum somewhat weakly punctured on the inner 

 side only. 



The structure of the head is very variable. The parietal ridges are usually long as in 

 L. bicolor in small specimens, and short as L. dentatus in larger ones. The latter usually 

 have the surface of the head densely punctured and the frontal area longer than broad ; 

 the former usually have the surface of the head more or less unpunctured and the frontal 

 area broader than long. Very small specimens are usually extremely flat like L. planus, 

 larger ones being somewhat stouter ; this is the case in L. bicolor also.
